Constructing an ecological security pattern balances ecological environmental protection with high-quality economic and social development. In this study, Guizhou Province is taken as the research area, and four ecosystem services functions-water production, soil conservation, habitat quality, and carbon sequestration-are evaluated. The optimal scenario identifies the priority protection area, representing the ecological source area, based on an ordered weighted average model. Ecological corridors are extracted using circuit theory to construct the ecological security pattern. The results show that: ① By setting and comparing the trade-off degree and protection efficiency under seven risk scenarios, the most optimal scenario was scenario 3, which had a low risk coefficient (α=0.5) and a relatively balanced background of the four ecosystem services. In this scenario, the protection efficiency of the four ecosystem services improved to varying degrees. ② The total area of ecological source areas was 29 688.72 km2, accounting for 16.85% of the total area of the study region, and its spatial distribution showed a pattern of concentration around the borders of the province and sparsity in the central area. ③ The total number of ecological corridors was 876, with a total length of 37 637.16 km, showing a "web-like" distribution, dense in the southeast and sparse in the northwest. ④ The eastern and southeastern parts of Guizhou were identified as ecologically important areas, the central part was an ecological control area, and the western part was an ecological improvement area. Additionally, a regional ecological development pattern of "three zones and two belts" was proposed, which includes major ecological corridors and ecological corridor restoration belts, providing scientific support for constructing and zoning the ecological security pattern of Guizhou.
Exploring the spatial and temporal differentiation patterns and driving factors of ecosystem service supply and demand in complex mountainous and hilly subsoil is of great significance for optimizing the regional ecological security pattern and sustainable development. Taking Chongqing as the research object, the spatial and temporal evolution characteristics of ecosystem service supply and demand in Chongqing from 2000 to 2020 and their driving factors were systematically revealed by using the InVEST model, the spatial autocorrelation analysis method, and the XGBoost-SHAP model. The results show that: ① The urban clusters of the Three Gorges Reservoir area in northeast Chongqing and the Wuling Mountain Area in southeast Chongqing exhibited a "high supply-low demand" pattern, while the main city metropolitan area exhibited a "low supply-high demand" pattern. From 2000 to 2020, carbon sequestration, habitat quality, and recreational supply declined, while water production and soil conservation supply first declined and then increased. Demand for carbon sequestration, water production, habitat quality, and recreation increased, while demand for soil conservation first declined and then increased. ② The supply and demand of ecosystem services in Chongqing maintained a dynamic balance in general, but the supply and demand deficits continued to expand in the main city metropolitan area, while the surpluses in the southeast and northeast areas of Chongqing remained stable. ③ The I of the ratio of ecosystem services supply to demand in 2000, 2010, and 2020 were 0.674, 0.666, and 0.679, respectively, with significant positive correlation in the space. The distribution characteristics were dominated by high-high aggregation and low-low aggregation, with high-high aggregation concentrated in the ecological barrier areas such as Chengkou County and Nanchuan District and low-low aggregation concentrated in the urbanization core areas such as Yuzhong District and Shapingba District. ④The XGBoost-SHAP model indicated that precipitation, urbanization rate, industrial output value, and the proportion of agricultural output value were the key driving factors influencing the relationship between supply and demand. The results can provide scientific references for regional ecological protection, ecological zoning control, and sustainable development.
As a critical ecological barrier in the upper reaches of the Two Rivers, Southwest China exhibits high habitat heterogeneity and significant urban-rural disparities. Investigating the coupling coordination relationship between ecosystem service supply-demand balance and human well-being is of great significance for regional sustainable development. Taking prefecture-level cities in the southwestern region as study units, this research measured the supply-demand relationships of five key ecosystem services: grain yield, carbon sequestration, water yield, soil conservation, and habitat quality. Combined with human well-being indicators, the study employed coupling coordination models and spatial autocorrelation analysis to reveal the spatiotemporal coupling patterns and spatial association characteristics of ecosystem service supply-demand and human well-being from 2000 to 2022. The results indicate: ① During the study period, the supply of grain yield and carbon sequestration increased, while water yield, soil conservation, and habitat quality supply declined. Demand for carbon sequestration, water yield, and habitat quality grew, whereas grain yield and soil conservation demand decreased. The supply-demand ratios of grain yield and soil conservation rose, while those of carbon sequestration, water yield, and habitat quality declined. Overall, ecosystem services maintained an ecological surplus (supply > demand) with significant spatial heterogeneity, with the Chengdu-Chongqing urban agglomeration and other high-intensity human activity areas showing a "low supply-high demand" deficit pattern, while western Sichuan and the Yunnan-Guizhou plateau maintained surplus conditions. ② The average human well-being index across southwestern prefectures at six temporal nodes was 0.207, 0.219, 0.248, 0.304, 0.356, and 0.371 respectively, demonstrating continuous improvement. ③ The coupling coordination degree between ecosystem service supply-demand and human well-being increased from 0.520 to 0.772, indicating significant improvement in their synergistic relationship and a shift toward more sustainable socio-economic and natural environment interactions. ④ During the study period, the global Moran's I values of the coupling coordination degree at the six time nodes were 0.486, 0.504, 0.438, 0.402, 0.414, and 0.306, respectively. The coupling coordination degree exhibited a significant positive spatial correlation, though both the spatial dependence and clustering characteristics showed a weakening trend. This indicates a gradual reduction in spatial heterogeneity and an evolution of the regional development pattern toward greater equilibrium. The research findings can provide a scientific basis for optimizing ecological conservation redlines, establishing differentiated ecological compensation mechanisms in Southwest China, and promoting harmonious coexistence between humans and nature.
Guizhou Province is an important ecological barrier in the upper reaches of the Yangtze River and the Pearl River. Karst landform in Guizhou is developed, with fragile ecological background. The ecological risk assessment and control of Karst landform are of great significance to ecological security and sustainable development of southwest China and the upper reaches of those two rivers. Based on the InVEST model and vigor-organization-resi-lience model, we quantitatively evaluated the ecosystem services and ecosystem health and constructed the ecological risk assessment model of Guizhou Province. With the help of GIS technology, spatial autocorrelation analysis method and gravity center migration model, we analyzed the spatial and temporal variations of ecological risk in Guizhou Province from 2000 to 2020. The results showed that ecosystem services in Guizhou Province increased from 2000 to 2020, with an annual average growth rate of 0.3%. The ecosystem health status was generally well and showed a good trend, and the annual average growth rate of ecosystem health was 12.6%. The ecological risk was dominated by medium ecological risk. The proportion of extremely low ecological risk area and low ecological risk area increased, the proportion of medium and above ecological risk area decreased, and the overall ecological risk showed a downward trend. The low ecological risk areas were mainly located in the south and southeast of Guizhou Province, while the high ecological risk areas were distributed in the central, western and northern parts of Guizhou Province. The global Moran's I of ecological risk in 2000, 2005, 2010, 2015, and 2020 were 0.856, 0.836, 0.844, 0.804, and 0.768, respectively, indicating that the positive correlation of ecological risk in spatial distribution, but the spatial correlation and spatial agglomeration characteristics were weakened. During the study period, the centroid and trajectory of ecological risk in Guizhou Province were consistent with the distribution area of its corresponding ecological risk. From 2000 to 2020, the spatial distribution pattern of ecological risk in Guizhou Pro-vince was relatively stable. With the evolution of time, the dispersion of spatial distribution of extremely high ecological risk and low ecological risk increased. Ecological risk assessment based on ecosystem services and ecosystem health would provide scientific basis for regional ecological risk management and control.
Building a reasonable ecological security network is a key for the coordinated solution in the contradiction between ecological protection and economic development. Taking Guizhou Province with typical karst development and a weak ecological background as an example, the cultivated land protection scenario, ecological protection scenario, and natural development scenario in 2030 were simulated based on the PLUS model. According to the landscape ecological risk index, landscape ecological security zones were divided into different scenarios, ecological source areas were identified by the ecological security zoning results and the InVEST-MSPA model, and ecological corridors and ecological pinch points were extracted by the circuit theory, to form an ecological security network for Guizhou Province in 2020 and 2030. The results showed that: ① The mean values of landscape ecological risks in 2020 and 2030 were relatively small, but the spatial distribution of ecological security zones was quite different, and ecological risks were generally higher in the northwest and lower in the southeast. ② The spatial distribution of ecological source areas was greater in the southeast and less in the northwest, which was consistent with the ecological risk pattern. The ecological sources were mainly patches with high habitat quality and strong landscape connectivity. ③ The number of ecological corridors extracted in 2020 (current situation) and in the 2030 cultivated land protection scenario, ecological protection scenario, and natural development scenario were 126, 56, 113, and 126, respectively; the number of ecological pinch points identified were 107, 67, 104, and 168, respectively; and the numbers of obstacle points identified were 54, 24, 69, and 69, respectively. ④ Guizhou Province is one of the three leading demonstration provinces of ecological civilization construction in China, and the protection of the fragile ecological environment is highly restrictive to economic development. The landscape ecological risk under the natural development scenario was low, and the layout of ecological safety network was more realistic; thus, this scenario met the two-way needs of ecological protection and economic development in Guizhou Province. The research results can provide a scientific reference for the division of the ecological safety zone and ecological security control in Guizhou Province in the future.
【Objective】 This paper is to propose a method to optimize ecological space zoning and develop scientific management strategies for watersheds. The focus is on clarifying the synergies and trade-offs among mountains, waters, forests, farmlands, lakes, and grasslands. 【Method】 The study takes the Hongfeng Lake watershed as a case study. It is a typical watershed consisting of mountains, water, forests, fields, lakes and grasses. Quantitative and qualitative methods were used to calculates synergies and trade-offs between these sub-ecosystems at both basin scale and local scale. The ecological zoning in the watershed was analyzed by considering the synergistic relationships between mountains, waters, forests, farmlands, lakes and grasslands. 【Result】 The study revealed significant spatial variation in ecological zones within the studied areas. It identified contrasting spatial relationships in the distribution of synergies and trade-offs, particularly between water and other subsystems, as defined by the water intersection line. Key findings include differentiated ecological protection roles of forests and grasslands, high pollution risks facing lakes, and the reliance on rainfall for agriculture outside regions where lakes effectively manage water storage. The watershed was classified into nine ecological control zones, including urban water source protection zones and ecological agricultural zones along the lake and its tributaries. Additionally, mountain areas were designated as ecological industrial development and conservation zones, water source conservation zones, and geo-hazard risk zones. 【Conclusion】 By analyzing the coordination and trade-offs among various ecological components, this study ensures the maximization of ecological diversity within each zoning type. The findings highlight the need for tailored management strategies across different zones to address their unique ecological needs and challenges.
Paddy fields are recognized as significant sources of methane(CH4)emissions,playing a pivotal role in global climate change.Elevated atmospheric carbon dioxide(CO2)concentrations(e[CO2])exert a profound influence on the carbon cycling of paddy fields.Understanding the effects of e[CO2]on CH4 emissions,as well as the underlying microbial processes,is crucial for enhancing carbon sequestration and reducing emissions in paddy fields.We reviewed the impacts of e[CO2]on CH4 emission in paddy fields,focusing on the activity,abundance,community structure,and diversity of carbon-cycling-related microbes.We also delineated the roles of various microbial processes in mitigating CH4 emissions under e[CO2],as well as the primary environmental determinants.Overall,the type of e[CO2]experimental platforms,duration of fumigation,concentration gradients,and the methods of CO2 enrichment all influence CH4 emissions from paddy fields.e[CO2]initially stimulates CH4 emis-sions,which may decrease over time,indicating an adaptability of the methane-emitting microbial community to e[CO2].This response exhibits a trend of initial attenuation followed by an intensification of the positive effects on CH4 emissions.Experiments with abrupt increase of CO2 concentration might overestimate CH4 emissions.The impact of e[CO2]on microbial processes is predominantly characterized by enhanced activities and abundance of methanogens,aerobic and anaerobic methanotrophs.It significantly alters the community composition and diversity of methanotrophs,with minimal effects on methanogens and anaerobic methanotrophic communities.Finally,we outlined future research directions:1)Integrated investigations into the effects of e[CO2]on CH4 emissions,methanogenesis,and both aerobic and anaerobic methanotrophs in paddy fields could elucidate the mechanisms underlying the impacts of climate change on CH4 emissions;2)Long-term studies are essential to understand the mechanisms of e[CO2]on CH4 emissions and associated microbial processes more accurately and realistically;3)Multi-scale(temporal and spatial),multi-factorial(CO2 concentration,temperature,atmospheric nitrogen deposi-tion,and water management practices),and multi-methodological(observational,data,and model integration)research is necessary to effectively reduce the uncertainties in assessing the response of CH4 emissions in paddy fields and related microbial processes to e[CO2]under future climate change scenarios.

Traditional villages have received widespread attention from all walks of life based on important carriers of Chinese rural culture. The mutual superposition of natural and cultural factors may exacerbate the evolution of traditional village geographical patterns. To understand such relationships and effects, factors and degrees influencing traditional villages need to be determined. Here, we analysed the data of 724 traditional villages in Guizhou recognised by relevant national ministries and commissions in China using average nearest neighbour analysis, Tyson polygon analysis, nuclear density analysis and Geodector. The geographic pattern feature revealed that traditional villages, in general, are highly clustered regionally and have significant edge effects on administrative units. Different substrate environments result in significant spatial heterogeneity in village spatial density, clustering, surface undulation, sun exposure, and waterfront. The geographic pattern of traditional villages is mostly affected by the closest distance to river valleys, the types and number of intangible cultural heritage resources in the county, river gorge density, edge effect index, degree of county ethnic language use, and proportion of paddy fields to the regional area; and their combined effects influence and control the community structure. The results highlight the impact of nature and culture on the distribution of traditional villages, which helps traditional village conservation and scientific exploration of human-land relationship issues in the mountainous areas of Southwest China.

赤水河流域在人类活动影响下,属于典型的生态脆弱区和水土侵蚀敏感区,水土流失严重且已影响到水质及周边生态环境安全.研究筛选降水侵蚀力(R)、土壤质地(K)、坡度坡向(LS)和地表覆盖(C)为水土流失敏感性影响因子,同时参考研究区石漠化分布情况,运用GIS技术研究贵州赤水河流域8个市县水土流失敏感性空间分布情况,引入水土流失潜在危险指数(SEPDI)评价水土流失敏感危险性.经过研究得出以下结论:①研究区水土流失敏感性属于中等偏上,其中中度和重度敏感区之和占总面积的63%;②各市县水土流失敏感危险性差异较大,危险性最大的是桐梓县,SEPDI为5.36,最小的是赤水市,SEPDI为3.4;③研究区水土流失潜在敏感性随坡度增加先增加后减少,25°~35°SEPDI达到峰值,35.以上的SEPDI下降,这是由于研究区地貌主要为高原山地,人类在8°~35.活动频繁,35.以上人类活动减少、植被增加,水土流失敏感危险性下降;④耕地与未利用用地水土流失风险性更高,土壤表面的覆盖对水土保持至关重要.
Water resource vulnerability in ecologically vulnerable karst areas is a key issue for regional sustainable development and the sustainable use of water resources. In this study, geographical information system (GIS) and remote sensing (RS) technology were employed to explore the vulnerability characteristics and spatial distribution of water resources in Guiyang City. The water resource vulnerability indicator in Guiyang ranged from 0.10 to 0.59, with an average value of 0.26. Yanglongsi Town, in Xifeng County, in the northern and main central urban area exhibited the highest water resource vulnerability, whereas Huaxi District in the south, and regions around Hongfeng Lake and Baihua Lake, in Qingzhen City, exhibited the lowest water resource vulnerability. Water resource vulnerability was predominantly mild, accounting for 35.85% of the total land area, followed by moderate (28.99%), with some non-vulnerable areas (13.60%) and very few extremely vulnerable areas (3.20%). Compared with traditional methods, the proposed index selection and assessment method, based on GIS/RS, are both scientific and intuitive. In addition, the results are presented in detail, accurately reflecting the actual situation of water resource system vulnerability.
